This is a two-page lithograph featuring the Cepheid Variable Star RS Puppis, an example of a special class of bright pulsating stars whose light and energy outputs vary over a set period of time. The text on the lithograph explains the historic...(View More) importance of Cepheid variable stars as distance markers. The accompanying classroom activity In Search of … Cepheid Variable Stars is a curriculum support tool designed for use as an introductory inquiry activity. During the classroom activity, students use the images and text on this lithograph to generate questions about Cepheid variable stars. They will conduct research to answer their questions and will create a presentation to demonstrate their understanding of the material, providing supporting evidence from their research.(View Less)

This image from the Hubble Space Telescope reveals a panorama of turbulent star birth, located close enough to Earth that Hubble can resolve individual stars. The star factory resides 170,000 light-years away in the Large Magellanic Cloud, a small...(View More) satellite galaxy of our Milky Way. Included are suggestions for using this in the classroom and an introductory activity in which students use the images and text on this lithograph to generate questions, and research answers, about star formation.(View Less)

Students work in groups to investigate one of the following factors driving climate change: greenhouse gases, sea level rise and melting sea ice. The investigation involves conducting an experiment, connecting to real-world data and presenting a...(View More) poster summary of their findings. The lesson includes experiment procedures (with pictures), a rubric for poster evaluation, a Powerpoint presentation (incorporating NASA videos), extensions, and additional resources.(View Less)

The Cosmic Times Gallery Walk and Cosmic Times Jigsaw lessons serve as extensions to the Cosmic Times suite of curriculum support materials. They are intended to provide an introduction to Cosmic Times as a whole, giving students the larger picture...(View More) of how our understanding of the universe has changed over the last century. During the Gallery Walk lesson, students peruse the Cosmic Times posters to answer open-ended questions. During the Jigsaw lesson, students work in cooperative teams to understand the primary scientific advances over the past century that have contributed to our current understanding of the universe.(View Less)

This program uses NASA data and resources to promote authentic classroom research experiences. These two complementary guides lead students through the process of conducting their own inquiry-based research on an Earth-focused topic. In their...(View More) guidebook, students read content and answer questions about each step in the research process- from formulating a question to sharing results. The separate guide for teachers provides explicit instructions, lists the standards addressed, and includes additional hints, resources and websites.(View Less)

This module focuses on ultraviolet radiation on Earth and in space and how it affects life. Learners will construct their own "martian" using craft materials and UV beads. They will explore how UV radiation from the Sun can affect living things,...(View More) comparing conditions on Earth and Mars, and then discuss ways in which organisms may protect themselves from UV radiation. They will then take part in a Mars Creature Challenge, where they will change their creature to help it survive harsh UV conditions — like on Mars. They will then test their Mars creatures by subjecting them to different environmental conditions to see how well they "survive" in a martian environment. This investigation will explore shelter and protection as one of life’s requirements and how Earth’s atmosphere protects life from harmful UV radiation. It also includes specific tips for effectively engaging girls in STEM. This is activity 5 in Explore: Life on Mars? that was developed specifically for use in libraries.(View Less)

This is an activity designed to develop a working definition of life. Learners will conduct a simple experiment, looking for signs of life in three different "soil" samples. The experiment introduces children to the difficulty that scientists face...(View More) in defining life. By observing the soil samples, participants try to determine if any contain signs of life and work to identify, refine, and create a set of characteristics that may be used to identify living versus nonliving things. The activity concludes with the development of a group definition of life. This group definition will be referred to in subsequent activities. It also includes specific tips within each activity for effectively engaging girls in STEM. This is activity 1 in Explore: Life on Mars? that was developed specifically for use in libraries.(View Less)

Learners will record detailed observations of a simulated surface and core sample of Mars, analyze a simulated surface and core sample of Mars, compare and contrast an unknown foreign object with the surface and interior of Mars, and learn...(View More) preliminary facts about Mars, its surface, and its place in the Solar System. The lesson uses the 5E instructional model and includes: TEKS Details (Texas Standards alignment), Essential Question, Science Notebook, Vocabulary Definitions for Students, Vocabulary Definitions for Teachers, three Vocabulary Cards, and a Mini-Lesson. This is lesson 2 of the Mars Rover Celebration Unit, a six week long curriculum.(View Less)

Learners will review what they have learned about scientific and engineering investigation, construct a valid scientific question that can be answered by data and/or modeling, and choose an appropriate mission for their rover that will answer their...(View More) scientific question. The lesson uses the 5E instructional model and includes: TEKS Details (Texas Standards alignment), Essential Question, Science Notebook, Vocabulary Definitions for Students, Vocabulary Definitions for Teachers, four Vocabulary Cards, and supplements on Writing a Scientific Question and Mission Choices. This is lesson 5 of the Mars Rover Celebration Unit, a six week long curriculum.(View Less)

This is a lesson about generating hypotheses and testable questions. Learners will use critical thinking and a collaborative approach to pose questions related to the study of Mars and evaluate the quality of their questions. They will explore...(View More) remote-sensing data collected by a camera orbiting Mars - the Thermal Emission Imaging System (THEMIS) and develop a team science question. Students will practice critical thinking skills, use a collaborative approach to this first critical step of the scientific process. Exploring the images of the surface of Mars in Visible (VIS) images, students will come up with a topic of study, their team science question and hypotheses. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes and vocabulary.(View Less)
